Definitions

• Travel path is recorded by a position encoder.
• predetermined setpoints e.g. Binary outputs of the control can be activated or deactivated.
• These electronic "switching points" can, e.g.
• the current actual value of the speed of the travel path that triggers a change in state is measured cyclically in a fixed time pattern
• the current speed value must be taken into account in a so-called “adjustment path, taking into account the response time, in particular in the form of a constant, of the equipment of the technical system to be controlled "This is the distance that is covered during the reaction time of the equipment to be controlled, until it has fully engaged, along the triggering travel path of the first equipment, ie until the trigger has finally been reached ⁇
• Send travel setpoint The triggering travel setpoint must be "shortened” by the size of this speed-dependent adjustment path, so that when the travel setpoint is actually reached, the operating equipment to be controlled is fully in operation Intervention, i.e. whose response time has expired.
• the following division is usually carried out in a complex manner to determine this adjustment path:
• Adjustment path 3 "Current actual value of the speed along the triggering travel path of the first item of equipment"
• the invention is based on the object of taking into account the response time of an operationally switchable operating means of a technical system when actuating the same when so-called waymarks are reached on a travel path of another operating means which can be run at variable speeds by means of a control can be achieved with little effort, in particular without discrete division.
• the current actual value of the triggering travel path of the corresponding equipment is again recorded and saved as a "final actual value”.
• a so-called “lead path” which is dependent both on the current traversing speed along the triggering traversing path and on the individual reaction time of the equipment to be controlled is formed by forming a difference between the “final actual value” and “starting actual value”.
• the stored setpoint values serving as waymarks along the triggering travel path are corrected by this lead distance by reduction, i.e. So-called “corrected travel setpoints” are formed. If the operating means concerned is actuated when the current actual value of the travel path reaches the size of a “corrected travel setpoint”, the response time of one of the stored trips when the corrected value is reached The equipment to be controlled is compensated for, since the output of a control is then activated sufficiently in time before the original size of the travel setpoint is reached.
• this reserve path VW which advantageously contains both information regarding the current travel speed and the individual reaction time of the equipment to be controlled, in the sense of a feedforward control, on the one hand, in that all setpoint values along the travel path When they are reached, the corresponding operating means are to be actuated by the current size of the travel path.
• this consideration of the response time of a piece of equipment can be achieved by simple subtraction or addition arithmetic operations, despite a possibly fluctuating travel speed. Elaborate divisions are eliminated.
• the current actual value of the travel path provided by a position sensor is adjusted by the current, speed-dependent value of the lead path, ie by The unchanged travel setpoints of the "switching cam", which serve as start and stop values, are now compared with the "dynamized actual value" of the triggering travel travel, which is increased by the value of the speed-dependent travel travel. If both comparisons are met, the switching output is activated, otherwise deactivated.
